<p>This manual covers versions up to v4.0 of JpGraph. There are three main branches
of the library: </p>
<dt><span class="term">The "3.x.y" and "4.x.y" branch</span></dt>
<dd>
<p>The "4.x.y" series is the current one and is only intended to run
on PHP5 (>= 5.1) and PHP7.0. <br />
The "3.x.y" series is the previous one and is only intended to run
on PHP5 (>= 5.1). <br />
This code is optimized for use both with PHP as well as
the new (and bundled version) of the GD 2.x library. Hence this will
not work if you only have the older GD 1.x graphic primitive library
installed. However, all modern PHP installations since 2006 have
shipped with GD 2.x so this should not in reality be any
problem.</p>
<div class="caution" title="Caution" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Caution</h3>
<p>Please note that it is not possible to run the "3.x.y" series
on PHP7.0. If you need to run on PHP7.0 then you <span class="bold"><strong>must</strong></span> use the 4.x version of the
library.</p>
</div>
</dd><dt><span class="term">The "3.x.y-p" and "4.x.y-pro" branch (The pro-version)</span></dt><dd>
<p>This is in principle the same as the "3.x.y" or "4.x.y" branch with the
difference that the pro-version includes a number of additional
modules (see <a class="xref" href="pt05.html" title="Part V. Additional graph types available in the professional version">Part V. Additional graph types available in the professional version</a>) not available in the free
version. This includes both some additional graph types as well as
1D and 2D barcodes. In addition the professional license gives three
months of email support for installing and configuring the
library.</p>
